FIRE-POT ATTACHMENT.

Specification of Letters Patent.

Patented May 8, i917.

Application tiled November 10, 1916. Serial No. 130,534.

To f/ZZ fur/tom t may concer/1t.'

lie it knou'n that l, lnnns'r liiIMMion, a citizen of the United of America, residing at Detroit, in the county of illayne and fotate of l-.fliichigain have invented certain new and useful improvements in Firel ot Attachments, of which the following is a specication, refe nce being had therein to the accompanying drawings.

lt is the object of the invention to prov-ide a simple Aittacliment for furnaces by which the size of the lire-pot may be reduced to lesse the fuel consumption in moderate Weather. lt is a further object to obtain a construction Which will not interfere with the ordinary manipulation of the furnace and which will not become excessively heated so as to burn out With these objects in vieiv, the invention comprises the noyel construction as hereinafter set forth.

In the drawings:

Figure l is a vertical central section through the lire-pet of a furnace, showing my improvement applied thereto;

Fig. 2 is a similar section in a plane at right angles to Fig. l.

is the lire-pot of an ordinary furnace and are the grate bars arranged below said fire-pot and provided With a common shaking mechanism, such as the rock-arms il and connecting bar D. E is the furnace dome.

lilly attachment comprises a vertical division plate F, which extends in a central )lane transversely of the fire-pot, and a corperating horizontal plate G', Which closes the space on one side of the division plate. rhe plate F is suspended Within the pot, rably by lugs l'l at the opposite ends thereof, which engage the usual shoulder l on the lire-pot. The plate is also held in position by the tapering form of the fire-pot and by the fact that it is placed diametrically thereacross and therefore is too long to be displaced laterally. The lower edge of the plate F is also suiliciently above the grate oars B to permit the free rocking of the latter Without interference. The plate G is supported by a shoulder J upon the plate F and also by the ledge l of the lirepot. The plate F overlaps the inner edge of the plate G, as indicated at K. thereby preventing the latter plate from becoming displaced.

ln use, Whenever it is desired to restrict the size of the fire-pot the plates F and G,

which are of a size for insertion through the lire-door of the furnace, may be readily introduced into the fire-pot, the plate F being first positioned and the plate G then dropped into engagement therewith. `When in'place fuel is introduced into the uncovered compartment of the pot and the fire started. rlhe plate G by closing the top of the empty portion of the pet prevents short circuiting of the air which Would check the fire, and at the same time, the space below this plate and at one side of the plate F is in free air communication with the ash-pit. rllhus when the Contact of the hot fuel With the plate F causes it to rise in temperature a circulation of air Will be established, the hot air rising adjacent to said plate and descending along the cooled outer Wall of the fire pot and through the open grate spaces into the ash-pit. fiere it will displace the cooler air from the ash-pit which Will rise against the plate F and dissipate the heat thereof.

it any time when the full furnace capacity is required, the plates F and Gr can be readily removed and Without the necessity of drawing the fire. This removal may be facilitated by the arrangement of a hook L centrally of the furnace dome, ivith Which a pulley and line may be engaged to assist in lifting said plates.

lWhat l claim as my invention is:

l.. The combination With a fire-pot and a series of movable grate-bars arranged therebeneath and coacting therewith, of a division plate for-the fire-pot extending across the same and suspended to clear said grate-bars and permit shaking movement thereof, and a horizontal plate at the top of said division plate for excluding fuel from one side of the latter and preventing short circuiting of the air, the space beneath said horizontal plate at one side of said division plate being in fre-e air communication With the space below the grate to permit circulation of the air and cooling of said plates.

2. rlhe combination with a lire-pot and a series of movable grate-bars arranged therebeneath and coacting therewith, of a Vertical division plate extending diametrically across said lire-pot and suspended therein, With its lower edge clearing the grate bars, and a horizontal plate for closing the space at one side of said division plate and at the upper end thereof, said horizontal plate being supported on said division plate and abutting thereagainst to prevent lateral displacement, the space beneath said horizontal plate being in free air communication with the space below the grate.

3. The combination with a tapering firepot having an interior ledge and a series of movable grate bars arranged below said fire-pot and coacting therewith, of a division plate arranged in a vertical plane to extend diametrically across said fire-pot and conforming to the taper thereof, said plate having a ledge substantially on a level with that of the tire-pot, the lower edge of said division plate clearing said grate bars and its upper edge portion being supported at its ends upon said ledge of the lire-pot and a horizontal plate resting upon said ledges of the vertical plate and tire-pot and closing the space at one side of the vertical plate.

Gopies of this patent may be obtained for 4. The combination with a fire-pot hav- -ing an interior ledge and a series of movable grate bars arranged the-rebeneath and coacting therewith, of a vertical division plate eX- tending across said tire-pot and suspended therein with its lower edge clearing the grate bars, said plate being restrained against lateral 'displacement-by the tire-pot wall and having a ledge substantially oppositethat upon the ire-pot wall, and a horizontal plate supported on said ledges and restrained against lateral displacement by the Vertical plate, a space having :tree air communication with the space below the grate, being formed between the grate and said horizontal plate.

In testimony whereof I aiiX my signature.

ERNEST KIMMICH.
